Jiangsu PP Handle Butterfly Valve Manufacturer Phone Number, Wholesale, Price [Jiangsu Jiayuan Pipe Valve Co., Ltd.] The PP Handle Butterfly Valve, also known as the Polypropylene Handle Butterfly Valve, is a valve made of polypropylene (PP) material, featuring excellent properties such as high temperature resistance, acid and alkali resistance, and corrosion resistance. Below is a detailed introduction to the PP Handle Butterfly Valve: Material Excellence: Made of polypropylene (PP), it boasts superior corrosion resistance, high-temperature resistance, and wear resistance, ensuring long-term stable operation in harsh working environments. Good Sealing Performance: Generally utilizes a soft sealing structure, with sealing surface materials often being rubber or polytetrafluoroethylene, offering good sealing performance and effectively preventing medium leakage. Easy Operation: The handle operation method requires minimal torque, allowing for flexible and easy opening and closing, suitable for pipe systems of various diameters. Simple Structure: The butterfly valve is compact in size and light in weight, with flexible and convenient operation and a simple structure composed of only a few parts, making it easy to install and maintain. Good Flow Control Characteristics: When the butterfly valve is fully open, the thickness of the disc plate is the resistance to medium flow through the valve body, resulting in minimal pressure drop and good flow control characteristics. The opening and closing part of the PP Handle Butterfly Valve is a circular disc plate, with one pivot installed on each side of the disc-shaped seat base, perpendicular to the axis line and integrated with the disc-shaped seat. To open or close the butterfly valve, rotate the handle to make the moving ring rotate inward,带动 the disc-shaped seat to rotate together, thereby achieving the opening and closing action.
